The example I was thinking of was destructive copying. This is equivalent to being knocked out and carried to another place. It doesn't matter how far or if there is a time delay, since you don't experience this. It also doesn't matter if there is a causal connection, as there would be in teleportation or being knocked out and carried, or if the copying occurs randomly. There is no way for you to know from introspection how you have come to wake up in a new place. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
